I thought I'd do something a little different this week. So this weeks letter, E, is for Elbow!!!
The elbow is a complex joint which forms a hinge or ginglymus. What a great word!!
The elbow is where three bones, the humerous (upper arm bone), ulna and radius (the lower arm bones) meet.
The nobbly bit on the outside of your elbow is actually part of the ulna bone called the Olecranon.
When you hit your funny bone the sensation you feel is actually irritation of the ulna nerve which is the largest unprotected (by bone or muscle) nerve in the body. It runs from your shoulder all the way down to the tip of your little finger.
This useful info was sourced from Wikipedia.
Other 'interesting' facts about elbows;
It is physically impossible to lick your own elbow.
The length between the inside of your wrist and the inside of your elbow is roughly the same as the length of your foot!! Looks huge, but try it, it works!
This info came from a file in my head labelled 'Weird and Useless Information!'
Scientists have discovered that Octopuses and Squid have the ability to form 'part-time' elbows to help them eat. Strange but true!
And that came from a random google search for 'elbows'.
Hope you've enjoyed discovering more about your elbows!! To read more interesting ABC Wednesday posts from around the world please visit here.
